Comparison MSI MPG X870E EDGE TI WIFI vs Gigabyte X870E AORUS PRO ICE

The number of processor power phases provided on the motherboard.

Very simplistically, phases can be described as electronic blocks of a special design, through which power is supplied to the processor. The task of such blocks is to optimize this power, in particular, to minimize power surges when the load on the processor changes. In general, the more phases, the lower the load on each of them, the more stable the power supply and the more durable the electronics of the board. And the more powerful the CPU and the more cores it has, the more phases it needs; this number increases even more if the processor is planned to be overclocked. For example, for a conventional quad-core chip, only four phases are often enough, and for an overclocked one, at least eight may be needed. It is because of this that powerful processors can have problems when used on inexpensive low-phase motherboards.

Detailed recommendations on choosing the number of phases for specific CPU series and models can be found in special sources (including the documentation for CPU itself). Here we note that with numerous phases on the motherboard (more than 8), some of them can be virtual. To do this, real electronic blocks are supplemented with doublers or even triplers, which, formally, increases the number of phases: for example, 12 claimed phases can represent 6 physical blocks with doublers. However, virtual phases are much inferior to real ones in terms of capabilities — in fact, t...hey are just additions that slightly improve the characteristics of real phases. So, let's say, in our example, it is more correct to speak not about twelve, but only about six (though improved) phases. These nuances must be specified when choosing a motherboard.

Synchronization technology provided in the board with LED backlight (see above).

Synchronization itself allows you to "match" the backlight of the motherboard with the backlight of other system components — cases, video cards, keyboards, mice, etc. Thanks to this matching, all components can change colour synchronously, turn on / off at the same time, etc. Specific features the operation of such backlighting depends on the synchronization technology used, and, usually, each manufacturer has its own (Mystic Light Sync for MSI, RGB Fusion for Gigabyte, etc.). The compatibility of the components also depends on this: they must all support the same technology. So the easiest way to achieve backlight compatibility is to collect components from the same manufacturer.

The maximum RAM clock speed supported by the motherboard. The actual clock frequency of the installed RAM modules should not exceed this indicator — otherwise, malfunctions are possible, and the capabilities of the “RAM” cannot be used to the fullest.

For modern PCs, a RAM frequency of 1500 – 2000 MHz or less is considered very low, 2000 – 2500 MHz is modest, 2500 – 3000 MHz is average, 3000 – 3500 MHz is above average, and the most advanced boards can support frequencies of 3500 – 4000 MHz and even more than 4000 MHz.

The ability of the motherboard to work with RAM modules that support XMP (Extreme Memory Profiles) technology. This technology was developed by Intel; it is used in motherboards and RAM blocks and only works if both of these system components are XMP compliant. A similar technology from AMD is called AMP.

The main function of XMP is to facilitate system overclocking (“overclocking”): special overclocking profiles are “sewn” into the memory with this technology, and if desired, the user can only select one of these profiles without resorting to complex configuration procedures. This is not only easier, but also safer: every profile added to the bar is tested for stability.

The version of the M.2 interface determines both the maximum data transfer rate and the supported devices that can be connected via physical M.2 connectors (see the corresponding paragraph).

The version of the M.2 interface in the specifications of motherboards is usually indicated by the number of connectors themselves and by the PCI-E revision provided for in each of them. For example, the entry “3x4.0” means three connectors capable of supporting PCI-E 4.0; and the designation “2x5.0, 1x4.0” means a trio of connectors, two of which support PCI-E 4.0, and another one supports PCI-E 5.0.

Operating modes of PCI-E 16x slots supported by the motherboard.

For more information about this interface, see above, and information about the modes is indicated if there are several PCI-E 16x slots on the board. This data specifies at what speed these slots can operate when expansion cards are connected to them at the same time, how many lines each of them can use. The fact is that the total number of PCI-Express lanes on any motherboard is limited, and they are usually not enough for the simultaneous operation of all 16-channel slots at full capacity. Accordingly, when working simultaneously, the speed inevitably has to be limited: for example, recording 16x / 4x / 4x means that the motherboard has three 16-channel slots, but if three video cards are connected to them at once, then the second and third slots will be able to give speed only to PCI-E 4x level. Accordingly, for a different number of slots and the number of digits will be appropriate. There are also boards with several modes — for example, 16x/0x/4 and 8x/8x/4x (0x means that the slot becomes inoperable altogether).

You have to pay attention to this parameter mainly when installing several video cards at the same time: in some cases (for example, when using SLI technology), for correct operation of video adapters, they must be connected to slots at the same speed.

The model of the audio chip (a module for processing and outputting sound) installed on the motherboard. Data on the exact name of the sound chip will be useful when looking for detailed information about it.

Modern "motherboards" can be equipped with fairly advanced audio modules, with high sound quality and extensive features, which makes them suitable even for gaming and multimedia PCs (although professional audio work will still most likely require a separate sound card). Here are the most popular modern audio chips: Realtek ALC887, Realtek ALC892, Realtek ALC1150, Realtek ALC1200, Realtek ALC1220, Realtek ALC4050, Realtek ALC4080, Supreme FX.

The motherboard has its own Bluetooth module, which eliminates the need to purchase such an adapter separately. Bluetooth technology is used for direct wireless connection of a computer with other devices — mobile phones, players, tablets, laptops, wireless headphones, etc.; connectivity options include both file sharing and external device control. The Bluetooth connection range is up to 10 m (in later standards — up to 100 m), while the devices do not have to be in the line of sight. Different versions of Bluetooth (at the end of 2021, the latest of which is Bluetooth v 5) are mutually compatible in terms of basic functionality and have all sorts of differences.

The type of LAN interface provided in the design of the motherboard. LAN (also known as RJ-45 and Ethernet) — a standard connector for wired connection to computer networks; can be used for both local and Internet. The type of such a connector is indicated by the maximum speed. Note that nowadays, even inexpensive "motherboards" are usually equipped with fairly fast LAN adapters — at least gigabit ones. The meaning of such characteristics is not only (and often not so much) to speed up the transfer of large amounts of data, but also to reduce lags in the network connection. This can be important for tasks that require good responsiveness or precise synchronization, such as online games.

— 1 Gbps. The standard used in the vast majority of desktop (non-server) motherboards. On the one hand, it provides more than a decent connection speed, sufficient even for large amounts of information; on the other hand, it is inexpensive and can be installed even in the simplest low-cost motherboards.

— 2.5 Gbps. An improved version of the gigabit standard, it is also a simplified and somewhat cheaper version of the 5-gigabit standard. It is found in separate "motherboards" for gaming purposes.

— 5 Gbps. A kind of transitional option between a relatively simple gigabit LAN (see above) and an advanced 10-gigabit LAN (see below). Found in some gaming motherboards....This standard costs less than the 10-gigabit one, while the communication speed still turns out to be quite decent, and the lags are low.

— 10 Gbps. Such a data transfer rate is indispensable for large volumes of information; in addition, it provides a high speed of passing individual data blocks, which is important for reducing lags in online games. At the same time, this interface appeared relatively recently and is not cheap. Therefore, it is mainly used in top-end "motherboards" for gaming and server purposes (see "In the direction").

— 100 Mbps. A very popular standard in its time, which is now considered obsolete in light of the spread of faster versions of the LAN. It is extremely rare, mainly in separate low-cost boards.
